I would prefer to use grape juice is supposed to be really healthy. The Kirkland Signature Newman's Own grape juice that I buy from Costco says it has 40g total carbohydrates and 39g sugars in 8oz. I don't mind paying extra to drink grape juice if it'll have a health benefit over just consuming plain sugar.

Is the carbs/sugars from the 8oz. of grape juice the right 'type' to have with creatine or do I need a mix of dextrose, maltodextrose and grape juice?

Thanks.
